M in has referenc to grease cups, of Kind which are commonly carried 01the connecting rod of purpose of holding lubricants for the bean theends thereof. 1 common form less devices com rises a bushing adapted 0be seated. in an opening in the connecting rod, and provided wi h a plugor follower, movable therein. On account of the vibration incident tothe movement of the engine, these plugs tr. 'uently work out of thebushing, and are lost. The principal purpose of my invention is toprevent such loss, without interfering with the custcn ary op eration ofthe plug, to adjust the same in the bushin i also provide an extensionfor the bushing having a feed-tube at its lower end which separates thehrasses in the end of the connecting rod, and aids in preventing wearthereof.

Said bushing is also provided with aninternal thread 2 for engagement with the threads on a plug 3, in theouter face 0' which is an opening i, forthe applitool in turning theplug 3, to move it deeper into the bushing, or reinov the same, as dbushing is "formed into a v-Jrench head 5, two

tion 10, and by means of en 11 projection, or handle, the plate can lie1' when desired.

will he seen that when the plate 8 is in position, it will pr vent anyremoval of the plug 3, accidentally or otherwise, and at the time the opning 9 in such plate will 761111lt access to the plug, to turn the samewi a tool, in the usual manner. Such plug turned inwardly when it isdesired to force the oil downwardly, into the wearing is of thecoiniocting-rod.

The bushing is provided with an exten- 1 1011, consisting of strips 11,ending in a tube .2, which is designed to be positioned beween theconnecting-rod brasses, when the bushing is in place, and direct thelubricant thereto. lt also'tends to hold such hrasses apart, as the somebecome worn around the crank-pin, so that the oiling operation will nothe interfered with. In case there is some wear about the tube 12, thiscan be adjusted by seating thereon a sleeve, as shown in broken lines at13, giving additional thick ness to the tube.

he end 1% of the plate 8 is of such a shape, that for emergency purposesit can be inserted in the opening at of the plug, to adjust the positionthereof.

What I claim and desire to secure, is:

1. In combination with a greasecup bushing, provided in its head with apair or" oppositely disposed recesses, and a plug adjustably held insaid bushing, and provided in its outer face with tool-engaging means;of resilient plate having a central openng, and provided with extensionsadapted l -ror engagement with said recesses, to hold said plate inposition.

2. in combination with a grease cup bushing, provided with catchengagingmeans on opposi'e sides of its head, and a plug adjustably held in saidbushing, and provided on its outer face with tool-engaging means; aspring plate provided with a central opening )erinitting access to saidplug; catches on the ends of said plate adapted to cooperate with saidcatch-engaging means, to hold said plate removably in position on saidbushing; and a handle on said plate for the operation thereof.

3. In combination with a grease-cup c eadily detached,

bushing, provided with catchengaging means on opposite sides of itshead, and a plug adjustably held in said bushing and provided on itsouter face With tool-engaging means; a spring-controlled flexible plateprovided with a central opening permitting access to said plug; catcheson the ends of said plate adapted to cooperate with said catch-engagingmeans, to hold said plate removably in position on said bushing; and 10a handle on said plate for the operation thereof.

In testimony whereof I afiix my signature.
